= A sweep trigger signal rms noise in div.
When the Word Recognizer supplies a trigger in synchronous mode, the trigger
jitter of the associated trigger signal is <1 ns; in asynchronous mode, the
associated trigger signal jitter is <20 ns.
N = number of averages during measurement interval.

2-1
for Delay or Delta Time.
= (measured frequency) x (measurement interval) for Frequency or Period.
Measurement Interval = 0.5 s or two periods of measured signal,
whichever is greater.
